Abstract: The present invention includes a novel sintered component (1) and a method of production thereof. The method including creating (100) a plurality of sub¬ components (10) using binder jetting additive manufacturing; the sub-components (10) having an outer surface (20) including one or more protruding portions (22, 24) having one or more bonding faces (26) configured to interface with at least one of the one or more bonding faces (26) of a neighbouring sub-component (1) and a recessed portion (28) for defining a cavity (30), in the sintered component (1), between sub-components (10); heating the plurality of sub-components (10) in a first heating step (104); assembling (106) said sub-components (10); heating the assembly of sub-components in a second heating step (108).
